The Exotic Electro-Optics subsidiary of laser components maker II-VI has signed two multiyear agreements to sell its sapphire windows to Lockheed-Martin .

The first agreement is for Lockheed's F-35 Lightning electro-optical targeting sensor, the only sensor that combines forward-looking infrared (FLIR) and infrared search and track (IRST) functionality integrated into the Warfighter's fuselage and housed behind sapphire windows.

The second agreement is for the shroud assembly of Lockheed's Sniper Advanced Targeting Pod, or ATP, which is the most widely deployed targeting system for fixed-wing aircraft used by the U.S. Air Force. It's also used by the air forces of 12 other nations.

II-VI's Exotic Electro-Optics division is the world's largest producer of large format sapphire windows, according to the company. Its products are typically assembled into a structural housing or shroud where electrical grounding or connectivity is required to facilitate EMI shielding or heating for anti-ice and anti-fog requirements.
